The type species H. roseus is phylogenetically confused, because two isolates (BCC 3381 and BCC 8808) were transferred to Tubeufia Penz. & Sacc., five isolates of Luo et al. (2017) were transferred to Pseudohelicomyces Y.Z. Lu et al., and one isolate (CBS 283.51) of Tsui et al. (2006b) is misidentified (Lu et al. 2018b). Although the sequence data of H. roseus is lacking, Lu et al. (2018b) named the clade comprising four freshwater species as Helicomyces sensu stricto. The epitype or reference specimen of H. roseus is needed to confirm the conclusion of Lu et al. (2018b).

Type species: Helicomyces roseus Link

Other accepted species: Species Fungorum – search Helicomyces.
